Buy a new ignition key switch lock cylinder with new keys to fix your issue and door lock cylinders if you don't want to carry 2 keys. A poorly cut key or worn out one will cause this problem. - https://www.ebay.com/itm/NEW-GMC-GM-OEM-IGNITION-KEY-SWITCH-LOCK-CYLINDER-2-DOOR-LOCK-CYLINDER-2-KEYS/351956362573
19Sil replied to 56napco's topic in 1999-2013 Silverado & Sierra 1500I drive my 1999 silverado every day with abs power connection unplugged underneath cab. Brake and ABS lights are turned on the dash, but brakes operate exactly like my 1990 k1500. When it is plugged in, the abs motor runs constantly.
99 silverado with 2000 2500 dash plunged right in and everything is perfect except mileage...Takes 30 minutes or more for trans temp needle to move. With cooler and fan my short box never heats up...
I had similar problems with my 99 Silverado. After extensive research it ended up being two things. The alternator and the instrument cluster. First I had the alternator tested and was told it was good. Then I replaced the instrument cluster with one from eBay. It helped some but was still slowly killing the battery, so I put a new alternator on and that finally fixed mine.
